Abstract
The pervasive acceptability of a revolution from monodirectional push-based media broadcasting to a bidirectional interactive pull-based internet protocol television (IPTV) has spotted significant development in recent years. The pervasive acceptability is because of the mammoth number of exhilarating television (TV) channels that IPTV offers. However, the channel switching feature of a TV system requires additional development despite the increased implementation of IPTV systems worldwide. Subscribers of IPTV services must be able to swiftly explore live TV stations and video contents of interest seamlessly, but zapping delay is a deterrent that occurs during a channel change that causes a significant glitch in IPTV systems. Many of the literature approaches such as channel prediction based on behavior analysis have shown flaws in resolving zapping delay. The approach of this study uses adaptive channel switching with a personalized electronic program guide to resolving zapping delay. The resolution saves the subscribers the time of channel navigation by eliminating the need to search for channels they want to view.
Highlights
The pervasiveness of internet protocol television (IPTV) coupled with the evolution of digital broadcasting services is rapidly emerging as a substitute for orthodox television (TV) broadcasting delivery systems [1]
Due to the aforementioned challenges faced by channel recommendation systems in IPTV, an approach based on adaptive channel switching with an electronic program guide is reported in this paper that can help to minimize zapping delay in IPTV at the subscriber level
This implies that one set-top box (STB) will receive unicast traffic from another STB rather than from the central server. This strategy will generate buffer overrun on the STB of a subscriber, which will result in zapping delay. It is understandably difficult for a network provider to deliver a reduced channel zapping latency as a feature to consumers of an IPTV system, but it is unavoidable a requirement for customer quality of experience (QoE) [25]
Summary
The pervasiveness of internet protocol television (IPTV) coupled with the evolution of digital broadcasting services is rapidly emerging as a substitute for orthodox television (TV) broadcasting delivery systems [1]. Different ways have been proposed in the literature to assist subscribers in swiftly locating their preferred channels of interest They include a recommendation system, an electronic program guide (EPG), and a search engine [5, 6]. EPG which is a multilayer program schedule is used to assist subscribers in channel switching It contains program information such as titles, names, exact start and end times, and playing periods. Due to the aforementioned challenges faced by channel recommendation systems in IPTV, an approach based on adaptive channel switching with an electronic program guide is reported in this paper that can help to minimize zapping delay in IPTV at the subscriber level.
